titleProject Scope Syntax

system.db.runNamedQuery(path, [parameters], [tx], [getKey])

  • Parameters

String path - The path to the named query to run. Note that this is the full path to the query, including any folders.

Dictionary[String, Any] parameters - A Python dictionary of parameters for the named query to use. [optional]

String tx - An transaction ID, obtained from beginNamedQueryTransaction. If blank, will not be part of a transaction. [optional]

Boolean  getKey - Only used for Update Query types. A flag indicating whether or not the result should be the number of rows affected (getKey=0) or the newly generated key value that was created as a result of the update (getKey=1). Not all databases support automatic retrieval of generated keys. [optional]

  • Returns

Any - The results of the query. The exact object returned depends on the Query Type property of the Named Query: typically either a dataset when set to Query, an integer representing the number of rows affected when set to Update Query, or an object matching the data type of the value returned by a Scalar Query.

titleSimple Example - With Parameters
# This example runs a Named Query while passing some parameters in the Project scope.
# The Named Query is assumed to have two parameters already defined on the Named Query:
# param1 : A string
# param2 : An integer

# Create a Python dictionary of parameters to pass. 
paramsparameters  = {"param1":"my string", "param2":10}
 
# Run the Named Query.
